Computer Assisted/Aided Qualitative Data AnalysiS (CAQDAS) is the use of computer software to aid qualitative research such as transcription analysis, coding and text interpretation, recursive abstraction, content analysis, discourse analysis, grounded theory methodology, etc.
Tools – analyse textual data:
- AnSWR is a software system for coordinating and conducting large-scale, team-based analysis projects that integrate qualitative and quantitative techniques.
- ANTHROPAC‘s analytical tools include techniques that are unique to Anthropology, such as consensus analysis, as well as standard multivariate tools such as multiple regression, factor analysis, cluster analysis, multidimensional scaling and correspondence analysis. In addition, the program provides a wide variety of data manipulation and transformation tools, plus a full-featured matrix algebra language.
- ATLAS.ti helps researchers uncover and systematically analyze complex phenomena hidden in text and multimedia data. The program provides tools that let the user locate, code, and annotate findings in primary data material, to weigh and evaluate their importance, and to visualize complex relations between them.
- CAT is a free service of the Qualitative Data Analysis Program (QDAP), and hosted by the University Center for Social and Urban Research, at the University of Pittsburgh, and QDAP-UMass, in the College of Social and Behavioral Sciences, at the University of Massachusetts Amherst.

- CDC EZ-Text is a software program developed to assist researchers create, manage, and analyze semi-structured qualitative databases.
- HyperRESEARCH is a software tool designed for qualitative analysis. The free edition is suitable for teaching the basics of qualitative research, without requiring students to purchase the full package. You can also use the Free Limited Edition to explore HyperRESEARCH’s capabilities.
- HyperTRANSCRIBE is ResearchWare’s software product for transcribing audio and video files. It lets you open and play most popular audio and video formats, and provides both graphical and keyboard control to play, pause, and loop playback so your hands never have to leave the keyboard.
- MAXQDA supports all individuals performing qualitative data analysis and helps to systematically evaluate and interpret texts. It is also a powerful tool for developing theories and testing the theoretical conclusions of the analysis. It is used in a wide range of academic and non-academic disciplines, such as in Sociology, Political Science, Psychology, Public Health, Anthropology, Education, Marketing, Economics and Urban Planning.
- Nvivo software supersedes N6 (NUD*IST 6), Non numerical Unstructured Data Indexing Searching and Theorizing software, is a robust and reliable program, appropriate exclusively for qualitative research analysis. It includes the very features of N6 and much more – including the ability to work with PDFs, surveys, photos, video and audio files. NVivo 9 also allows you to open and work with projects you’ve developed in N6.
